As per Section 124 of the Income Tax Act, Where AO has been vested over a jurisdiction over an area, he has jurisdiction on
a) person carrying on Business/Profession in that area
b) Branches of persons who has principal place of business in his area
c) Any person residing in that area.
Now, say if a person named 'X' is residing the area on rent given by the owner of the property 'Y'. Does AO of that area has jurisdiction on 'X' only or 'X' and 'Y'?
